Mix flour, sugar, baking soda, and salt together in a large bowl. Mix in buttermilk, eggs, and melted butter. Stir wheat germ into the batter last.
Heat a lightly buttered griddle over medium-high heat. Drop batter by large spoonfuls onto the griddle and cook until bubbles form and the edges are dry, 2 to 3 minutes. Flip and cook until browned on the other side, 2 to 3 minutes more. Repeat with remaining batter.
